CVE-2025-24794·Python vulnerability

The Snowflake Connector for Python provides an interface for developing Python applications that can connect to Snowflake and perform all standard operations. Snowflake discovered and remediated a vulnerability in the Snowflake Connector for Python. The OCSP response cache uses pickle as the serialization format, potentially leading to local privilege escalation. This vulnerability affects versions 2.7.12 through 3.13.0. Snowflake fixed the issue in version 3.13.1.

How likely is exploitation

FIRST's Exploit Prediction Scoring System puts the probability of this CVE being exploited in the next 30 days at 0.25% — higher than 16% of all published CVEs. EPSS is an independent forecast of exploitation, not a severity rating: it says nothing about how much damage a successful attack does, which is what a CVSS score measures.

Affected versions

From: 2.7.12

Until: 3.13.1

Fixed in: 3.13.1

How to fix this CVE

Update the Snowflake Connector for Python to version 3.13.1 or later to eliminate the pickle deserialization vulnerability in the OCSP response cache. This vulnerability allows a local attacker with elevated privileges to potentially escalate their access on systems running affected versions. Upgrading resolves the unsafe serialization mechanism that could be exploited to execute arbitrary code during certificate validation.

sudo dnf update python3 && sudo pip3 install --upgrade snowflake-connector-python==3.13.1

Defensia detects this vulnerability

How to check if you are affected

  1. Check installed Snowflake Connector version: python3 -c "import snowflake.connector; print(snowflake.connector.__version__)"
  2. Verify the package location: pip3 show snowflake-connector-python | grep Version
  3. Search application logs for OCSP certificate validation failures: grep -i 'ocsp\|certificate' /var/log/application.log
  4. Confirm remediation by re-running version check and ensuring version is 3.13.1 or higher

FAQ

What is CVE-2025-24794?

CVE-2025-24794 is a privilege escalation vulnerability in the Snowflake Connector for Python where the OCSP response cache uses unsafe pickle deserialization, allowing a local high-privileged attacker to potentially execute arbitrary code on the affected system.

Is CVE-2025-24794 being actively exploited?

No, this vulnerability is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog and no public exploits are available.

What versions of the Snowflake Connector for Python are affected by CVE-2025-24794?

Versions 2.7.12 through 3.13.0 are vulnerable. Version 3.13.1 and later contain the fix.

How do I check if my server is vulnerable to CVE-2025-24794?

Run 'python3 -c "import snowflake.connector; print(snowflake.connector.__version__)"' and compare against versions 2.7.12–3.13.0. If your version falls in this range, your system is vulnerable.

Does Defensia detect CVE-2025-24794?

Yes — Defensia's CVE advisory scanner compares installed package versions against the NVD database. If the Snowflake Connector for Python is installed on a monitored server, CVE-2025-24794 will appear in your dashboard with remediation steps.

CVE-2026-25632CVSS 10EPyT-Flow is a Python package designed for the easy generation of hydraulic and water quality scenario data of water distribution networks. Prior to 0.16.1, EPyT-Flow’s REST API parses attacker-controlled JSON request bodies using a custom deserializer (my_load_from_json) that supports a type field. When type is present, the deserializer dynamically imports an attacker-specified module/class and instantiates it with attacker-supplied arguments. This allows invoking dangerous classes such as subprocess.Popen, which can lead to OS command execution during JSON parsing. This also affects the loading of JSON files. This vulnerability is fixed in 0.16.1.
CVE-2026-34938CVSS 10PraisonAI is a multi-agent teams system. Prior to version 1.5.90, execute_code() in praisonai-agents runs attacker-controlled Python inside a three-layer sandbox that can be fully bypassed by passing a str subclass with an overridden startswith() method to the _safe_getattr wrapper, achieving arbitrary OS command execution on the host. This issue has been patched in version 1.5.90.
CVE-2026-33054CVSS 10Mesop is a Python-based UI framework that allows users to build web applications. Versions 1.2.2 and below contain a Path Traversal vulnerability that allows any user supplying an untrusted state_token through the UI stream payload to arbitrarily target files on the disk under the standard file-based runtime backend. This can result in application denial of service (via crash loops when reading non-msgpack target files as configurations), or arbitrary file manipulation. This vulnerability heavily exposes systems hosted utilizing FileStateSessionBackend. Unauthorized malicious actors could interact with arbitrary payloads overwriting or explicitly removing underlying service resources natively outside the application bounds. This issue has been fixed in version 1.2.3.
CVE-2026-28505CVSS 10Tautulli is a Python based monitoring and tracking tool for Plex Media Server. Prior to version 2.17.0, the str_eval() function in notification_handler.py implements a sandboxed eval() for notification text templates. The sandbox attempts to restrict callable names by inspecting code.co_names of the compiled code object. However, co_names only contains names from the outer code object. When a lambda expression is used, it creates a nested code object whose attribute accesses are stored in code.co_consts, NOT in code.co_names. The sandbox never inspects nested code objects. This issue has been patched in version 2.17.0.
CVE-2026-26030CVSS 9.9Semantic Kernel, Microsoft's semantic kernel Python SDK, has a remote code execution vulnerability in versions prior to 1.39.4, specifically within the `InMemoryVectorStore` filter functionality. The problem has been fixed in version `python-1.39.4`. Users should upgrade this version or higher. As a workaround, avoid using `InMemoryVectorStore` for production scenarios.
